ABSTRACT:
Solar cell having a contact formed from a titanium group element in contiguous relationship with the cell, a mixture of a titanium group element and a platinum group element overlying the titanium group layer, and a layer of a platinum group element overlying that layer. A body of silver or other contact metal is adhered to the platinum group layer. The three layers may be vapor deposited on the semiconductor body, while the silver layer is more advantageously applied by plating or electroplating.
